Since lot of player confused about mod types and patches, I give a short list which category what can do:

• Customized things for yourself! (drs, slp, wav, ini)
• Change an already exists graphics/terrain to something else
• Change an already exists sound to something else
• Change an already exists texts to something else
• Edit player's colors
• Changing interface looks (uncommon)
• Adds Random maps or Scenarios

• New things + what Visual mods can already for everyone in your room! (.dat + drs, slp, wav, ini)
• Change/edit units, buildings, objects behaviors, stats, cost, etc
• New terrain rules (example: ships on land)
• Edit minimap's colors
• Change/edit technologies/researches
• Edit graphics rules (example: unit's attack graphics slower or faster)
• Sound played at different place (example: wolf howling always at background)
• Gives new sounds
• Edit tech tree, civ/team bonuses
• Gives new civs (a bit complex)

• New options! (dll editing)
• More difficult to edit and need programing skill to make it
• Mostly not used with .dat file to make it compatible with other mods
• Can edit interface/menu options and buttons
• Possible new features (cut out from aoe beta) or even more
